Original application filed September 22, 1925, Serial No. 57,872. Divide 1927. Seria1 No.18l6,7 55.

In the drawing, Fig. 1 is a plan view of mechanism embodying the present invention.

Fig. 2 is a detail section on the line 22 of Fig. 1,

Fig. 3 is a longitudinal section on the line g at its upper and lower ends, a threaded open- 33 of Fig. 1,

Fig. 4 is a detailview of a bracket (20H? stitutingithe end member of a. roll-support1ng yoke. l 1 v A portion of a husking roll is shown at 8,

and itwill be understood that'the rolls are arranged in pairs and that the adjacent surfaces of members of each pair move clownwardly, the husks being-caught by the rolls and passed between them while the stripped ears are passed longitudinally over the rolls and delivered at the end of the machine. Motion is imparted to the rolls through gearing at the upper ends of some of the rolls right angle brackets 83 which are in turn the husking rolls. Each yoke consists of a lower bar 26 which is secured rigidly to the frame of the corn-husking machine, and an upper bar 27 which may be of the sameform and dimensions as the lower bar and is ar-' ranged parallel therewith. The trunnions or shafts of the rolls arejournaled in hearing blocks. or boxes 30 which fit closelybetween the yoke members 26 and 27, and that block or box which receives the trunnion or journal of the outer roll has its upper and lower sides grooved whereby-it may slidably engage the yoke bars 26 and 27. The block or boxreceiving the trunnion or shaft of the d and this application filed April 26 inner roll is, however, held against lateral movement by the stay bolts 31' inserted through the] said bars adjacent thesides of the box. It will be readily understood that by this arrangement the outer roll may yield to the thickness of a stalk or other article passing between the rolls so that the proper operation of the parts will be effected and the usual springs (not shown) are provided to maintain the operative relation ofthe rolls. 1

To close the ends of the yokes, we employ brackets 67 one of which is shown in detail in .Fig. 4. This bracket is a. single integral casting including a short standard 68, a lateral base plate 69 at the lower end of the standard, and flat leaves 70 on its inner side ing 71 being formed through the standard. The ends of the yoke bars rest upon and are bolted to the leaves 70, and the base 69 rests upon and is bolted to the sid'e bars of the machine frame, the opening 71 providin 'a hearing for the spring-adjusting screw. '1 llS construction isstrong anclpermits the yoke to be assembled 'before being placed in the machine inasmuch as the securing bolts are; notflinserted through thelower yoke bars butare inserted through the-baseplates 69- at one side of the yoke bars. g

The ends'of the gear case are secured to the case to carry a cross rod 85. The case comprises aback plate 86 providedwith openings whereby it may be fitted on the trunnions at the lower ends of the husking rolls, against the bearingstherefor and be tween the bearings and the gears. The case also includes a box or trough consisting of a short-back wall 87, a bottom 88,a front wall 89, and end walls 90integrally united.

.In assembling these parts,,the trunnions' of the husking rolls areengaged through the bearingblocks in the yoke, and the back plate 86 is slipped on the ends of the trunnions. The gears are then secured on the ends of the trunnions, the plate 86 being thereby retained in place, after which the case or trough, with lubricant in it and the brackets 83 secured thereto, is raised into position so that the back plate 86 will pass into the case in front of the short back wall 87, the brackets 83 being then bolted rigidly to the main frame. The cover 91 con sists of a plate of proper dimensions to extend over the entire case and the yoke and may be rigidly securedupon the yokeby the stay bolts 31 therein. The ear-guiding fingers tit) are permanently attached to the cover at the back end thereof, and the lower ends of the divider bars 92 are also secured upon the cover at the back edge thereof, although other means for guiding the discharging ears may be provided. The cover is also provided with openings 93 giving access to the oil cups 94: in the bearings 30 whereby lubricant is supplied to the bearings. The front edge of th cover has rolled portions 95 encircling the rod 85 so that the cover is firmly supported in its proper position, and on the under side of the cover is secured a strip 96 which returns to the case any grease thrown up by the gears 24 and the respective retaining cotter pins and prevents such grease running along the cover. The upper portion of the front wall 89 is bent toward the gears, as at 97, to prevent grease being thrown out by the centrifugal action and also to provide space for the rod 85.

The husked ears pass over the cover 91 into a chute 98 which directs them into a conveyor by which they are carried to a bin or other receptacle. The chute is shown as hingedly supported on the rod 85 and its front end may be suspended from the operators platform by a chain 99 so that it may be raised and prevented from digging into the bottom of the conveyor when the latter is folded.

Grease is fed into the case through an opening in the top thereof which is normally closed by a cover 100.

It will be noted that the gears are entirely enclosed and may run in oil. If the bolts securing the brackets 83 and 84 to the frame be removed, the gear case may be withdrawn downwardly, without disturbing the gears or the cover which will be supported on the yoke, and the changing of the oil or cleaning of the case is thus facilitated. When thus removing the case or trough, the chute may be swung upwardly and rearwardly to rest upon and be supported by the cover.

Having thus described the invention, we claim:

1. In a corn-basking machine, the combination with driven rotatable elements, and gearing connecting the ends of said elements, of a shield extending over the gearing, and a gear case completely housing the gearing below the shield, the shield constituting a cover for and being secured independently of the case and the case being movable upwardly into position around the gearing and removable downwardly from the gearing.

2. In a corn-husking machine, the combination of a yoke carrying bearings for driven rotatable elements, gearing connecting the ends of said elements, a back plate fitted on the ends of the driven elements and disposed between the gearing and the bearings in the yoke, a gear case having an open top and movable upwardly to extend around the back plate and the gearing, and a cover extending over the "use and theyoke and secured independently of the case.

3. In a corxrhusking machine, the combination of a yoke carrying bearings for drivon elements, gears connecting the ends of said elements, a back plate fitted on the ends of the driven elements between the yoke and the gears, a gear case acting with the back plate to house the gears, and a cover extending over the case and the yoke, there being an oil deflecting strip on the under side of the cover within the case.
